Description:
We present a study of discrete radio sources in the Magellanic Clouds
(MCs) using the latest large-scale radio surveys made with the Parkes
radio telescope between 1.4 and 8.55GHz. These surveys achieved higher
sensitivity than previous surveys done with the Parkes telescope and
so the number of discrete radio sources detected towards the MCs has
increased by factor of five. Also, we have obtained improved
positions, flux densities and radio spectral indices for all of these
sources.
A total of 483 sources towards the Large Magellanic Cloud (LMC) and
224 towards the Small Magellanic Cloud (SMC) have been detected at at
least one radio frequency. Most of the MC's sources have been
classified in one of three groups: SNRs, HII regions or background
sources according to classification criteria established here. In
total, 209 discrete radio sources in the LMC and the 37 sources in the
SMC are classified here to be either HII regions or SNRs. We
investigate their luminosity functions as well as the statistics of
background sources behind the MCs. Also, we examine the distribution
of SNRs and HII regions in the MCs.
